Question : Will the new iTunes allow my old songs bought in the iTunes Music Store onto a new iPhone, iPad, iPod, etc.?

Hello,
    Just like a zillion other people, I want to update my Apple mobile device. I have an iPod Nano 1G that still cooks pretty well, but I want to get that new iPhone and probably an iPad later. I've bought a bit of music in the iTunes Music Store that I've already put on the Nano, and would like to know if iTunes is going to give me a hard time when I try to put those songs on the new iPhone (or iPad, etc.). Some songs are DRM-free (bought @ $1.29), but I'd say half of the purchased songs are the $0.99 DRM variety. Please let me know the # of allowed mobile devices, any helpful links, etc. Thanks.
